Kubernetes 应用要求⚓︎

1 Kubernetes 的集群地址⚓︎

  • 集群填写的是 K8S 的集群地址。
  • 直接访问集群地址页面可以显示如下信息(如: https://10.1.13.67:6443)，一般是 master 节点的 6443或8443 端口。

kubectl config view --minify

apiVersion: v1
clusters:
- cluster:
    certificate-authority-data: DATA+OMITTED
    server: https://10.1.13.67:6443
  name: kubernetes
contexts:
- context:
    cluster: kubernetes
    user: kubernetes-admin
  name: kubernetes-admin@kubernetes
current-context: kubernetes-admin@kubernetes
kind: Config
preferences: {}
users:
- name: kubernetes-admin
  user:
    client-certificate-data: REDACTED
    client-key-data: REDACTED

2 获取 Token 方法⚓︎

  • 下面以 ko-admin 为例，如果你的系统中没有此账户可以使用其他有权限的账户或者新建。

kubectl get secret -n kube-system
